SPECIFICATION forming part of Letters Patent No. 352,530, dated November 16, 1886. Application filed April 29, 1886. Serial No. 200,500. l

(No model.)

To all whom it` may cfncern.-

Beit known that I, JAMEs FATKIN, a citizen of the United States, residing at Winifrede, in the county of Kanawha and State of West Virginia, have invented certain new and useful Improvements in Wrenches; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which` V .wherein- Figure l is a perspective view of a wrench constructed in accordance with my invention. Fig. 2 is a side view thereof; and Fig. 3 is a plan View, partly in section.

Similar letters of reference indicate similar parts throughout the several views.

A indicates the handle of the wrench, of a size and shape adapted to the particular use for which it is intended.

B indicates the stationary jaw, of hook shape, as shown, the hook-groove being of a form adapted to readily encircle a pipe, rod, or other like article.

The body of the wrench is provided with two raised shoulders or cheek-pieces, C C, between which is pivoted at D the movable jaw E, as shown in Fig. 3. This movablejaw is provided upon its face with ridged or serrated projections L, enablingit to firmly grasp, during its operation, the pipe or similar article held between it and the fixed jaw. Itis pivoted eccentrically betweenthe cheek-pieces, and is held in the position shown in full lines in Fig. 3 by means of a band-spring, F, attached to the side of the wrench and bearing against the front portion of the movable jaw. The spring is curved outwardly, as shown, and the front of the movable jaw is rounded off, so as to permit the said jaw to be moved outward into the position shown in the dotted lines in Fig. 3, when the wrench is to be disengaged from the article operated upon. In such position the free end of the spring rests Wit-hin the hollow H of the movable jaw, and the upper surface of the jaw forms a continuation ofthe hook-groove ofthe stationaryjaw.

rlhe body of my improved wrench is prefer- .ably made of cast-steel and the movable jaw jaw having a rounded projection in front of 7o the pivot, and a retaining-spring outwardly curved at its free end, and bearing against the said rounded portion of the movable jaw, substantially as described.

2. A hand-wrench consisting of an operating-handle, a stationary hook shaped jaw,

cheek-pieces projecting from said handle in front of the stationary jaw, a movablejaw pivoted between said cheek-pieces, said movable jaw having a rounded projection in front of the pivot, a iiat surface upon its opposite side, a hollowed-out vportion in front of the rounded projection, and a retaining-spring outwardly curved at its free end, bearing against the said rounded portion of the movable jaw, the free end of the spring being adapted to rest within the hollow portion of the movable jaw when such jaw is open, substantially as described.

In testimony whereof I affix my signature in y presence of two witnesses.
